Around 2002 Namco wanted to reboot their Xevious series of shoot ‘em up, by creating a new 3D Xevious for Playstation 2. The team hired for this mission was Project Aces, the same people behind Ace Combat 04: Shattered Skies and the following Ace Combat games. You can imagine this would have been the perfect team to develop a new Xevious, thanks to their great 3D engine and experience with Ace Combat.
Unfortunately it seems Namco considered this Xevious remake to be less profitable than a new Ace Combat. After creating an early prototype using Ace Combat 4 engine and a few Xevious 3D models, Project Aces was moved to develop Ace Combat 5: The Unsung War.
A video from the Xevious PS2 prototype was shared by Project Aces on Twitter when they reached 5.000 followers.
